Giant cell arteritis is also known as cranial arteritis or temporal arteritis. This is a medical condition involving inflammation in the arteries situated in the temple area. This leads to pain and tenderness in the temple area, where the hardened arteries can be felt.
[edit on Wikidata] An opportunistic infection is an infection caused by pathogens (bacteria, viruses, fungi, or protozoa) that take advantage of an opportunity not normally available, such as a host with a weakened immune system, an altered microbiota (such as a disrupted gut flora), or breached integumentary barriers.
The precise type of opportunistic infection (bacterial, viral, fungal, or protozoan/parasitic) that occurs depends on the type and extent of immunologic alteration, whether it is cellular, humoral, phagocytic, or a combined defect; and on organisms present inside and outside the body.
